SPECIFICATION forming part of Letters Patent No. 443,673, dated December30, 1890.

Application filed July 26, 1890, Serial No. 359,991, (N0 inodel.)

To aZZ whom, it may concern.-

Be it known that we, ABEL II. FROST and FRED L. BRYANT, of Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Mat tress-Making Machines; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to improvements in wire-coiling machines adaptedto automatically weave coiled-wire fabric for bed-bottoms. lleretoforemachines for this purpose have embraced a table upon which the fabriclies while being made and a coiling-machine arranged at one end of saidtable and run by hand or other power. Before the end of the wire strandis thrust forward into a marginal coil of the fabric being woven thesaid fabric has been moved longitudinally toward or from the coilerabout half the width of a coil in order to insure the entrance in thesaid marginal coil of the end of the strand of which a new coil of thefabric is about to be made. l Vhen each coilhas been completed,tl1efabric has been moved bodily across the machine a distance equal toabout half thelength of one twist of the coil for the same purpose.

These two movements have in some cases heretofore been accomplished bymoving the coil by hand and in some cases by having automatic mechanismfor bringing the final coil or the fabric into linear position for theinsertion of the next coil and for moving the final coil longitudinallyafter the completion of the same.

In the present invention we desire to retain the coiled fabric upon thetable as it is being made and to move the coiling mechanismlongitudinally to and from the fabric before a coil is to be formed andto also move said coiling mechanism after a coil is formed transverselyadistance equal to about one-half the diameter of the coil. In otherwords, the fabric is held on the machine while the coiling device orfabric-making mechanism is moved transversely and longitudinally, asrequired.

To this end as well as to the production of a cheap and durable machinethe invention a machine embodying our invention. Fig. 2 is a sideelevation of the same. Fig. 3 1s an end or rear elevation of themachine. Fig. 4

is a transverse sectional view of a portion of the machine, taken uponline 4 4 of Fig. 2, looking in the direction indicated by the arrows andomitting the upper portion of the machine, embracing the coilingmechanism. Fig. 5 is a sectional view on line 5 5 of Fig. Fig. 6 is asection on line 6 6 of Fig. 5. Fig. 7 is a plan view of one of themovable tables on which the coiling devices are supported.

The coiling mechanism,consisting of the feed-rolls and thecoiling-spindle and means for operating the same herein shown, aresubstantially the same as shown in our former patent, No. 296,551,granted April 8, 1884, and are simply here used for the purpose ofillustrating the invention, as any other coiling devices may be used.lVe do not, therefore, minutely describe these parts, but here refer tothe said patent for a more complete eXplanation of the construction andoperation of said coiling mechanism.

It will subserve the purposes of this invention to state that the wireis fed into the coiling apparatus A at a and is forced out of the sameover the coiler proper at a the several parts of the coiling apparatusbeing mounted upon a table or platen A.

B is the frame of the machine proper, composed of the standards 6, upperand lower longitudinal side beams b 12 and upper and lower end ortransverse beams b 5 Supported upon the side beams 17 by the standards bis a table B. It is upon this table that the fabric is made and allowedto remain immovably in position as each new coil is added thereto oruntil the entire fabric is completed. The table B does not extendentirely to the end of the machine, as more clearly shown in Figs. 1 and2. At the rear end of the machine and resting upon the beams 12 we placethe transverse tracks B. These tracks support the two carriages here'-inafter to be mentioned and the table A.

The first or lower carriage consists of two transverse beams C, unitedat their ends by rods or bolts c, the beams C resting upon and adaptedto be moved freely upon the tracks B The beams C, as will be noted,extend across or transverse of thetracks and carry upon their upperfaces runners or tracks C. It is upon these runners or tracks C that theupper table C is loosely fitted and adapted to move. The table A restsupon and is secured to the upper table C 1) is a shaft supported insuitable bearings d from the frame of the machine, at the end thereof,(see Figs. 1 and 3,) carrying upon its end a flanged pulley-wheel (1.Power may be transmitted to this shaft from a suitable source of supplyby means of a belt passing over the pulley d. The shaft D is providedlongitudinally with a groove (Z Mounted loosely upon the shaft D isaspindle or sleeve D, provided with a suitable feather adapted to enterand slide in the groove (Z of the shaft D, so that said spindle orsleeve will rotate with the shaft D, while at the same time it may bemoved longitudinally thereon between the bearings d. Secured upon oneend of the sleeve D is a flanged pulley-wheel d over which a belt (1 istrained, so as to connect a similar pulley-wheel (1 mounted upon thecoiling-table, and by which the necessary power to operate the coilingmechanism A is obtained from the shaft D. By reason of the featheredconnection of the shaft- D and the sleeve D we are enabled to have thecoiling mechanism in operation constantly while carrying the latter toand fro across the table. It will also be noted that by reason of thebelt connection (1 the coiling mechanism may be moved to and from theshaft D a short distance without interfering with the transmission ofpower to the latter.

' E is a shaft mounted in suitable hearings in the frame of the machine,and to which power may be supplied by any suitable means. The end of theshaft projects beyond the transverse bar I)" and is there provided witha wheel E. The outer face of this wheel is provided with two sets ofcogs or teeth 6 e, the intermediate portions 6 of the face being smoothand free from obstruction. Secured in bearings 6 upon the end standardsZ) of the frame is a worm or screw-threaded shaft E Near one end of thisshaft E is a beveled wheel or pinion E the teeth of which are adapted toengage the teeth 6 c 011 the wheel E. F is an arm or bracket, the upperend of which is rigidly secured to the lower carriage by means of boltsf passing through its end and engaging one of the transverse beams C.The lower end of this arm F is provided with an enlargement or block f.Within this block f is a cam-plate F, having a pin or stud thereon whichproj ectsthrough the face of the block f, to which the handle f issecured, so that the said plate F may be rotated within the block f. Oneither side of the shaft E is a nut f Each nut is provided with a pin orprojection which enters a suitable slot in the disk or plate F, so thatthe rotation of said plate F will move the two nuts toward or away fromthe shaft E -that is, into and out of engagement with saidscrew-threaded shaft. This is a familiar mechanical construetion. Anyother well-known means for securing the arm F so that it will travellengthwise of the shaft E as the latter is rotated may be employechifdesired.

It will be obvious from the above construet-ion that when power isapplied to the shaft E, so as to rotate the same, and the bar or arm Fis engaged with the shaft E by a movement of the handle f every rotationof the wheel E will cause the shaft E to be rotated intermittently-thatis to say, the pinion E will first engage, say, the teeth 6 of the wheelE and will be rotated until the space 6 comes opposite the pinion Ewhereupon the shaft E will remain stationary, while the wheel Econtinues to rotate. Shortly thereafter the teeth 6 engage the wheel Eand again the shaft E is rotated. When the shaft E is rotated, it worksin the engaging-nuts f and consequently will move the arm F and theparts engaged therewith so long as the shaft E is rotated, and as soonas the said shaft ceases to rotate the arm F and the parts securedthereto remain stationary. In this manner the lower carriage and theceiling mechanism are moved across the table intermittently. The lengthof this travel or movement obviously depends upon the number of teeth (2e. As here shown, the number of teeth is sufficient to cause thecarriage and coiling mechanism to move forward a dlstance equal to aboutone-half the diameterof acoil. Should itbe desired to run two strands ofwire in the same coil, one of the sets of teeth 6 or e may be omitted.

To give the coiler a movement upon the lower carriage to and from thefabric the following mechanism is employed: A shaft G is mountedtransverse of the machine in suitable bearings g, located upon the lowerside bars 0 At either end of this bar G are rigidly secured the links G,the upper ends of which are enlarged to afford bearings for a spindle orconnecting-bar G which latter is rigidly secured in said upper ends ofthe links G. Secured beneath the center of the table C by the bolts g isa yoke or bracket G which passes over and is loosely engaged with theupper bar G Any rotation or oscillation of the lower shaft G istransmitted to the upper bar G by the rigidly-connected links G. Thebracket G is consequently given an oscillatory movement forward andback, the length of throw depending, of course, upon the oscillationgiven to the shaft G.

The shaft G is operated by the following mechanism: Upon the shaft E ata point inside of the cross-bar b of the frame the disk II is mounted,said disk having upon a portion of its face it a circumferential flangeconstituting a cam 72. Upon the shaft G is rig- ITS idly secured an armH, the upper end of which is adapted to engage the face 7t and the cam hof the wheel H. To lessen the friction at this point we find itconvenient to provide the upper end of the bar or arm H with afriction-roller 72?, loosely mounted over a stud 7L3 secured in the endof the arm H. A spring H is interposed between the arm H and thetransverse bar I). Said spring tends to draw the upper end of the bar Hat all times against the cam wheel or disk H. It will be manifest thatthe rotation of the wheel H will cause the upper end of the arm H tooscillate forward and back, as the friction-wheel h first engages theface 72, and then rides upon the cam h, and then drops back again to theface h of the wheel H, and also that this forward-andbackward oroscillatory motion of the upper end of the arm H will be communicated tothe upper table 0 through the medium of the shaft G, the links G, thebar G and the bracket G For the purpose of properly effectin g thisoscillatory movement of the table 0", which in practice is aboutone-half an inch in length, the said table 0 is mounted somewhat looselyupon the tracks 0'.

The coiling apparatus and the carriages upon which it is mounted travelacross the machine in the direction indicated by the arrow in Fig. 1,starting nearest the pulleywheel (1. YVhen it is desired to return thetables and coiling apparatus to that side of the machine, the handle fis operated and the nuts f thereby loosened,whereupon both tables may bemoved bodily across the machine, the nuts f not then being engaged withthe worm-shaft E lVe do not desire to be limited to the specitic devicesherein illustrated and described for rocking intermittently the lowertable C nor to the mechanism for giving the longitudinal movement to thecoiling devices, inasmuch as other well-known mechanisms will readilysuggest themselves to skilled mechanicians, and because the essentialfeature of our invention does not consist in the details of the devicesherein shown.
